The Vicor QPO-1LZ-01 is an output ripple attenuator that utilizes active filtering to reduce periodic and random disturbances (PARD). It offers over 30 dB of PARD attenuation across the frequency range of 500 Hz to 500 kHz. This device operates within a voltage range of 3 to 30 VDC and can handle load currents as high as 10A.
The QPO-1LZ-01 features a closed-loop architecture that enhances transient response and ensures quiet point-of-load regulation. It supports precise point-of-load regulation and offers up to 99% efficiency. The attenuator is available in a low-profile LGA package and comes in dimensions of 25.3 x 25.3 x 5.0 mm for a lidded SiP or 24.9 x 24.9 x 4.4 mm for an open-frame SiP.
This ripple attenuator is suitable for applications such as Telecom Base Stations, Point of Load Power Systems, Sensors Requiring Low Noise Power, and Medical Instrumentation. Its ability to reduce output ripple and improve transient response makes it a valuable component in noise-sensitive power systems.
